Answer 7

one way is to do

f(n) + g(n) = [11] + [-2(n-1)]

f(n) + g(n) = 11 - 2(n-1)

notice how 11 is the first term and -2 is the common difference

Answer 8

I have honestly no idea what you're expected to do

Answer 9

you could also do f(n) - g(n), but that leads to a different common difference

Answer 10

then plug 31 for n?

Answer 11

wow my tags worked

Answer 12

yes ty b

Answer 13

`then plug 31 for n?` yes correct @rebeccaxhawaii

Answer 14

okay so 11-2(31-1)
11-2(30)
11-60
f(n)+g(n)=-49??

Answer 15

looks good

yay thank you c:

Answer 17

no problem
